by a measured movement of an object, the device comprising an optical module having at least one a laser comprising a chamber for fabricating a ray-illuminated light beam; an optical member for directing a beam of radiation to a plane adjacent to the object, and a conversion member for converting the reflection and modulation by the object The ray of the ray beam is an electrical signal, and the conversion member is formed by combining the chamber of the laser and the measuring member for measuring a change in the chamber during the operation. The reflected radiation entering the chamber causes 'which represents the movement of the object relative to the module, the optical module comprising a laser mounted on a mounting plate, the chamber parallel thereto, and the optical member An optical component is mounted that is mounted on the mounting plate and aligned with the laser, from which the measuring beam of light emitted from the laser travels to the flat near the object . One such device is particularly suitable for use as an input member for a personal computer, and the function often referred to as a mouse on this document can be replaced. The device is also more suitable for use as a reel or click device in a portable device, such as for use in a mobile phone, commonly referred to as a reel menu. In a printer or scanner, the movement of the input or output medium can be detected by the unit. The invention also relates to an operational method of fabricating such devices, and an operational method for measuring the motion of an object with the aid of such devices. [Prior Art] A U.S. Patent Application Serial No. 90 891. doc 1 358 655 2002/0104957, which is incorporated by reference in its entirety, is hereby incorporated by reference. In this context: - see Figure 9a - the input device is shown on a shelf, the erection plate is formed as a foot that matches the erection pin, a laser is placed in parallel with its chamber The erection board. The device contains three of these lasers that are assembled at an angle of 120 degrees (see Figure 9b). Around the laser, an annular body is mounted, and a focusing mirror is formed on the inner side thereof to guide a measuring beam of light emitted by the laser through a lens to a window, the window is in the cover of the module in. A portion of the ray is reflected from the process to a moving animal and then returns straight to the chamber of the laser. The chamber and the measuring member together form the reflected beam-converting member, and in a chamber, a relative movement of the object is indicated. For example, the == is a component that measures a change in the impedance contained in the laser chamber. A line detector is also suitable for this purpose. The disadvantage of this conventional device is that it is not sufficiently small for many applications. For smaller applications such as smaller sizes are required. In particular, mass production of such devices is not easy and inexpensive. SUMMARY OF THE INVENTION Therefore, the __ object of the present invention is to manufacture - such devices as stated in the introduction, which are particularly compact and inexpensive and easy to manufacture. Said in the introduction - the further optical parts comprising - the partition walls of the laser, and stacked, and at least the uppermost portion being near the plane of the object. The other party for this reason 'in accordance with the present invention, the device is characterized in that the device comprises - a piece of body directly on the erecting plate for projection viewing and the laser is not heavily optically transparent and the upper side forms the 90891 .doc 1358655 Face' This means that the device can be quite small. The measuring beam of light can be directed to the block (four) relative to the mounting plate. By this small angle, the ray beam can be reflected back and forth several times in the transparent portion of the block before reaching the upper plane. According to the invention, the result is that both the lateral dimension and the height of the device are defined, whereas the relatively large optical range of the radiation beam is created as required for the proper operation of the henry device. On the other hand, the most important part of the device, such as the laser, the optical component, which is exemplified by a mirror surface, and the block body, can now be attached to the erection by means of surface mounting. On the board. With the relatively high accuracy of the standard, and the quick and inexpensive assistance known as the pick and place machine, this can be done "because the block has absolutely no overlap with the laser in particular." It can be simply packaged in a transparent plastic material. The liquid transparent plastic material which is cured after application is particularly suitable for this purpose. Preferably, the block is directed to a side of a first portion of the transparent uppermost portion of the measuring beam of light and is inclined outwardly. This causes the measurement ray beam to be corrected for any interference entering the block. The amount of the angle of the side relative to the normal is, for example, 3 degrees. The uppermost portion of the block further includes a second portion disposed on the first portion, the sides of which are substantially perpendicular to the mounting plate. The ray beam can be reflected several times in this section. Preferably, the block is entirely made of a transparent plastic such as pMMA (PolyMethylMetaAcrylate) or polycarbonate (P〇lycarb〇nat hook. In a useful variation) the measuring member contains a ray disposed on the erecting plate Detecting _, and the optical component includes a focusing mirror disposed on a side of a further block of 90891.doc -9- 1358655, the further block device is disposed on the mounting plate, and the side is provided with a Further mirroring, the projection portion of the radiation emitted by the laser is on the radiation detector. In a preferred embodiment of an input device according to the invention, the laser, the side member and the optical The member is encapsulated in a hardened optically clear gel, which also includes the entire ray distance from the laser to the block. This results in at least one of the most vulnerable and sensitive parts of the device or module being small and priced. Inexpensive packaging. This also limits the number of medium transitions that may occur in reflection. The best results in this case can be obtained with a transparent plastic material. Preferably, the erecting plate An electric and thermal insulating material, and one side of the mounting plate is provided with a conductor unit, and the laser and the side member are connected to the conductor single 7L. This also contributes to the compactness of the device. In other words, the device is inexpensive 'because a large number of devices can be manufactured at the same time. The so-called printed circuit board (PCB) has a particularly suitable erecting plate. In an advantageous modification, the erecting plate has an opening 'near the laser, the opening of the laser at least its wall surface being covered by a thermally conductive material' which forms a heat sink of the laser or formed on the laser a thermal connection with the laser-heat sink. If the opening is completely filled with a material such as copper, the laser can be mounted thereon. If desired, the laser can advantageously Installed beside the opening, and as such, the conductive metal in the opening joins the laser to a heat sink of 90891.doc -10- 1358655 located below the erection plate. Such a change results in a reduction of the device Height dimension is possible or Talk about how the module is placed on the portion of the erection plate. According to the present invention, a method of operation for measuring the movement of an object relative to an input device is characterized by utilizing a photo according to the above conclusion The fact that the device is input. Because of this small size, the device is particularly suitable for use as an input unit, operating a so-called reel menu in the operation of a mobile phone. On a laptop computer, the device can also be advantageously The application is a commonly used pressure pad for a plurality of menu fingers. A method of producing a photoelectric input device, wherein the input is formed by an object being detected to move, and the device is coupled with an optical module, The module includes: at least one laser having a chamber for generating a measuring beam; an optical member for guiding the beam to a plane close to the object; and a conversion member for converting the reflection by the object The ray of the measuring beam is an electronic signal, wherein the converting member is used by the chamber and the measuring member of the laser to measure the operation a combination of variations in the interior caused by the interference of the reflected beam of the measuring beam of light - a constant wave that the measuring beam penetrates into the chamber and the chamber, which represents one of the object relative to the module For relative motion, the optical module is formed by a mounting plate on which a chamber is disposed parallel to one of the plates, and the optical member is formed by an optical component disposed on the erection plate and aligned with the ray Shooting for the measurement beam of light emitted by the laser, from which it is directed to the plane of the object, according to the invention, the optical member is characterized in that the device is equipped with a further optical zero. a piece comprising a body that is directly attached to the erection plate and adjacent to the laser, and 90891.doc •11- 1358655 does not overlap with the laser in any manner as viewed from a projection angle, and at least the uppermost The portion is optically transparent and its upper side forms a plane adjacent the object. In this way, a wheeled device according to the invention can be obtained. Preferably, the measuring member is constituted by a radiation detector, the device is mounted on the mounting plate and the optical component is formed as a focusing mirror and the device is on the side of the -step block body, the step block The body device is mounted on the erecting plate, and the side surface is provided with an n-step mirror surface, and the projection portion is irradiated with the radiation emitted by the laser to the radiation detector. , in the preferred embodiment of the invention, the optical member is covered with a liquid optically transparent gel which seals the path from the laser to the entire ray of the block, and after application hardening. Preferably, the electrical and thermal insulation material is selected as the material of the (four) plate, the surface of which is mounted with a conductor unit to which the laser and the measuring member are coupled. Thus, the most important portion is attached to the mounting plate 4 in a surface-adhesive manner, such as the laser 'the progressive optical component, the optical member and the measuring member. The part can be placed on the erection plate with the aid of a standard piek and plaee machine. In a particularly advantageous variant, such as the laser, further optical parts, the optical component or the material component (d) before the part of the calibration (4) is placed on the erection plate, the adhesive area is formed on the erection plate, the side dimension of the area in the basin is selected, and (4) the relevant part is placed on the side of the side of the erection plate The dimensions are almost the same. As a result, in the small correction of the position of the parts, the precise calibration of the relevant parts - 9089l.doc • 12 - 1358655 can be further improved - it can still be self-aligned ( The method of selfregisterin^ is borrowed (four) with the help of the area. The area with solder is particularly suitable for this purpose. In the process of melting the solder, the parts provided with the metal layer on the back are self-registered. In a manner, aligned with respect to the weld (four), such parts that do not require any electrical connection, such as the block and the further block, can also be advantageously adhered and calibrated by this method. For this purpose, such parts The bottom surface will be specially provided with a metal layer. The laser and the debt detector crystal will have one such conductive layer as the specification. [Embodiment] The drawings are not drawn to scale and have some dimensions, such as thickness. The size 'is exaggerated for clarity. In the different drawings, corresponding regions or portions, the same component symbols are given to the extent possible. The input device 10 shown in Fig. 1 includes a module n It has a mounting plate 4, here a printed circuit board 4. On this plate there is a conductor unit 9, here in the form of a copper region 9. A laser beam and a photodiode 3 are mounted Above them, a connection line 20 is used for the top of the laser and the top of the photodiode 3. The optical member 2 is placed in the form of a focusing mirror 2 on the laser 1 and the photodiode On one side of the body 3, the focusing mirror Receiving a measurement ray beam s from one of the laser 1 radiations, and guiding the erection plate at an angle of about 3 degrees to an in-step optical component (see FIG. 2 or 3), which is included in the laser A piece of body on one side of the beam that is positioned on the erection plate 4. In this embodiment, the module 丨丨 contains more than one laser 丨, 丨, of which only two are seen in the figure. The parts 2, 3 attached to each of the lasers i, 丨 are also indicated by the corresponding numbers. 90891.doc • 13· 1358655 The block 5 is here entirely made of a transparent plastic material called PMMA. The ray meter S enters (see Fig. 2) the block body 5, which is reflected by a first portion 5A of the uppermost portion 5A and after being placed in the portion of the first portion 5A1 - β 5A2 , reaching the upper plane v of the body 5, above which (see FIG. 1) there is a moving object Μ, for example, a paper, or as shown in the figure, a finger Μβ of the person operating the device 10 is moved Finger Μ The reflected ray travels in the opposite direction and reaches the chamber of the laser ,, which causes a change It appears to be a result of the movement of the finger caused by interference. In this embodiment, the occurrence of the change in the chamber of the laser cymbal is measured with the aid of a ray detector 3, which is here a photodiode 3, partially The ray emitted by the laser 1 is incident thereon. This can be accomplished with the assistance of a further mirror 7 (see Fig. 3) which is placed on one side of a further block 6, here also made of plastic material. The mirror 2, which reflects the ray beam S to the block 5, is mounted on the same side. The cavity to the further mirror 7 and the radiation detector 3 form a conversion member C' which converts the radiation reflected and modulated by the object into an electronic signal. Further details of the detection of the movement of the finger are shown in the above-mentioned U.S. Patent Application Serial No. 1; 82〇〇2/〇1〇4957. As shown in FIG. 2, there is an opening 12 in the mounting plate 4, and at least the wall surface of the laser bud is covered by a heat conducting material 13, which is copper here, which connects the laser 1 and the - (four) material 14, The heat sink is located on the side of the mounting plate 4 opposite to the laser 1. Each side of the first portion 5A1 of the uppermost portion 5 of the block 5 is simultaneously constructed to be outwardly inclined, and the method is 90891.doc -14 * * 1358655 line is 30 degrees. As a result, any reflection from the ray beam S can be offset when entering the block body $. The laser 1 and here, that is to say the rest, for example the photodiode 3 and the further block 6, are placed outside the block 5 from the point of projection, which is indicated in FIG. An obvious advantage. Figure 4 shows an important variation of the apparatus of Figure 1 in a schematic and perspective view. Here, a transparent package 8 can be seen, which can be easily applied because the overlap of the block 5 and the further parts 3, 6 is not present. The package 8 contains the entire ray path of the beam s between the laser and the block 5 and protects the parts by covering and contributes to the stable operation of the device 1 也是 also due to interference reflection Both are avoided, or at least limited. A thin further package (not shown) can be applied over the package 8 and is opaque to the radiation, if desired. The package 8 is here a ruthenium-based plastic material and is a material that is particularly suitable for this purpose. Further and better, as shown in Fig. 4, the upper plane v of the block 5 is curved. As a result, a user of the device (e.g., a mobile phone) into which the device is integrated can easily find and properly clean the plane. The apparatus according to the present invention, exemplified by the embodiment of the drawings, can be manufactured as follows, with the aid of the method of operation according to the present invention. The starting point (see Fig. 1 for example) is a printed circuit board 4 having an opening 12 whose wall is covered by a layer of copper 13. Above the upper side of the plate 4, a conductor unit 9 is placed to connect the active electrical components such as the laser 1 and the photodiode 3. In particular, for parts such as the laser 1 and the alignment of the photodiode 3, and also for the bricks 5, 6, the solder area (not shown) is applied to the 90891.doc -15· 1358655 This upper side of the plate 4, previously predetermined precise position. * iS ^ JL Φ u ^ ^ The dimensions of these regions are k疋 as the actual and the placed zeros ♦ such as laser 丨, photodiode 6 3 body 5, 6, the size is exactly the same . All of these parts 3, 5 have a metal layer on their bottom surface (also not shown and then with the help of the pick-up machine, the above-mentioned parts are placed relatively accurately on the solder area described above. Then with the board 4 Fixing occurs in the -welding process, whereby the small errors of the placed parts are automatically corrected. This provides the part 1, 3, 5, 6 of the module in a simple 'quick and inexpensive way' The charge is relatively accurate. After the surface of the parts, the additional electrical connections required for the active electrical parts can be accomplished by the connection line 2G. A thermal compression technique (plus compression) can be used for this. Then (see Fig. 4), a package made of plastic material in the form of droplets 8 is applied, which covers the laser 1' of the photodiode 3 and the mirror h is in the laser and the block 5 The ray path of the beam S can be found in the droplets. "The electrical connections of the active electrical components 丨, 3 (not shown) extend outside the package 8, or if needed Is located at the bottom of the board 4 After the package 8 has been hardened, for example by heating, the device 10 is ready for use. Due to the structure of the module, a large number of devices 10 can be easily manufactured at the same time. A segmentation technique such as 'they can be separated from each other. A single device i 〇 is about 30*30 gongs but the height is no more than 1 〇 public. The block 5 is 10 mm high. And the amount is, for example, 5 mm * 5 public. 90891.doc -16· 1358655 The present invention is not limited to the specific embodiment described, because for the expert, many variations within the framework of the present invention And modifications are possible.
